HYDROCARBON-VAPORIZER FOR EXPLOSlVE-ENGINES.

SPECIFICATION forming part of Letters Patent No. 644,027, dated February20, 1900.

Application filed September 18,1899. Serial No. 730,890. (N model.)

as an explosive mixture into the explosion- T0 (tZZ whom it mayconcern.-

Be it known that I,WILLIAM BAINES, a subject of the Queen of England,residing at London, England, have invented certain new and usefulImprovements in Vaporizers for Interrial-Combustion Engines, (for whichI have made application in Great Britain under No. 18,961, datedSeptember 5, 1898,) of which the following is a specification.

My invention has relation to a vaporizer forinternal-combustion engines,adapted also to serve as a silencer for the exhaust-gases from theengine; and among the objects in View is to provide a device of thedescribed character whereby the exhaustgases from the engine are causedto pass therethrough and at the same timeheat the hydrocarbon to bevaporized whether the latter is mixed with the air or not. Thus the heatof the exhaust is utilized for vaporizing the hydrocarbon and mixing itwith the air in a manner peculiarly suitable for the heavier mineraloils, while the temperature of the exhaust is reduced, causing lessnoise and smell.

The invention consists in the novel construction, arrangement, andcombination of parts, as hereinafter described, illustrated in thedrawings, and pointed outin the appended claims.

In the drawings, Figure 1 is asectional view, partly in elevation, of adevice embodying my invention. Fig. 2 is an elevation, partly insection, on line 4 4 of Fig. 1.

My vaporizer, which also performs the f unction of an exhaust-silencer,comprises a casing D, having a casing F secured thereto at one end, thetwo forming practically one casing and the construction being such thatthe exhaust-gases entering the silencer at the inlet D impinge on thedividing-wall F, which is arranged as shown, whereby to form the chamberF. The chamber F is divided by a horizontal septum F into twocompartments F F communicating at F The oil and the air are admittedinto the upper chamber F through the inlet-tube F pass into the lowerchamber F and being heated and vaporized in these chambers by theexhaust-gases pass chamber of the motor through the outlet F which is inpractice to be connected in any suitable manner to the inlet-valve ofthe motor.

Desirably the exhaust-gases pass from the casing D into the atmospherethrough an asbestos cloth, as shown at D It is evident that the chamberF may, if desired, be divided into more than two compartments byadditional septa, such as F*, so as to give greater length of travel tothe mixture of oil and air.

That I claim as my invention, and desire to secure by Letters Patent,is-- 1. In a device of the character described, the combination with thecasing of an exhaust-silencer, having an inlet at one end for admissionof exhaust-gases and an outlet at .the opposite end for the said gases,of a partition F within the casing, a second partition F forming thechambers F F com municating with each other at one end, the chamber Fcommunicating with an inlet for the explosive charge, and the chamber Fcommunicating with an outlet for the said charge.

2. In a device of the characterdescribed, the combination with thecasing of an exhaust-silencer comprising the casing D having an outletat one end for exhaust-gases, and a casing F secured to the casing D atone end and provided at the opposite end with an inlet for admission ofthe exhaustgases, of a partition F within the casing F and a partition Fforming two chambers F F communicating at one end with each otherthrough opening W, said chamber F communicatin g at the opposite endwith the inlet for the oil and air and the corresponding end of chamberF communicating with the outlet for the vaporized oil and air.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM BAINES.
